If f(x) = 5x^2– 3 and f(x + a) = 5x^2+ 30x + 42,
what is the value of a ?
Answers
Answer:
The zeros are x=0,3,-2
There is a multiplicity of 1 for all of them.
Step-by-step explanation:
The required value of a is 3 for the given function.
What are the functions?The function is defined as a mathematical expression that defines a relationship between one variable and another variable.
The function is given as follows:
f(x) = 5x²– 3
Substitute the value of x = x + a in the above function,
f(x + a) = 5(x + a)²– 3
f(x + a) = 5(x² + a² + 2ax) - 3
f(x + a) = 5x² + 5a² + 10ax - 3
f(x + a) = 5x² + 10ax + 5a² - 3 ....(i)
As per the question, we have f(x + a) = 5x²+ 30x + 42 ....(ii)
Equating the equations (i) and (ii),
So, 10a = 30
a = 30/10
a = 3
Therefore, the required value of a is 3.

Answer:

Step-by-step explanation:
the two angles are opposite so they are equal
Answer:
x = 35°
Step-by-step explanation:
Vertical Angles
When two lines cross, two pairs of angles are formed. Those who are opposed by the vertex are called vertical angles and they are always congruent.
Congruent angles have the same measure.
Thus, the angle marked as x is opposed to 35° and they have the same measure, thus:
x = 35°

Standard Form: Ax + By = C
Slope-Intercept Form: y = mx + b

Step 1: Define
Standard Form: x + 4y = 12
Step 2: Rewrite
Find slope-intercept form
Subtract x on both sides: 4y = 12 - xDivide 4 on both sides: y = 3 - x/4Rearrange: y = -x/4 + 3we know that
The equation of the line in the slope-intercept form is equal to

Solve for y
Subtract both sides
Divide by both sides
therefore

Answers
Answer:
u = vector (-6 , -6)
Step-by-step explanation:
u = vector(a , b)
Left (-) 6 units and down (-) 6 units
The translation vector for the image is (-6,-6).
What is a translation vector?A translation vector is a type of transformation that moves a figure in the coordinate plane from one location to another. Vectors are given in the form ( x y ) where x is the movement horizontally and y is the movement vertically.
For the given situation,
The image of a point (1, 2) under a translation is (-5, -4) .
The translation vector can be found by calculating the movement horizontally and vertically as
⇒ [tex](-5-1,-4-2)[/tex]
⇒ [tex](-6,-6)[/tex]
Hence we can conclude that the translation vector for the image is (-6,-6).
